The ore detected by the Geiger counter is the tip of an iceberg that is the largest known uranium deposit in the United States and among the largest in the world.
Now a company's bid to mine the 119 million pounds of the radioactive ore has churned up the political landscape in Virginia. Virginia's General Assembly is taking up the fiercely debated issue this session and it's a coin flip whether it will clear the way for the state to become the first on the East Coast to mine uranium.
Most uranium mining in the U.S. has occurred in the arid West. Virginia is prone to tropical tempests — some of historic proportions — and opponents fear a catastrophic storm could create an environmental nightmare if the mining and processing of the ore was allowed. Drenching rains and winds could carry radioactive waste to local waters that are used for drinking supplies in the state's largest city, Virginia Beach, and others in southeastern Virginia, they argue.
"We're looking at an extraordinary high-stakes gamble and it's not a gamble the state of Virginia should take," said Cale Jaffe, a leading voice against mining and director of the Charlottesville office of the Southern Environmental Law Center.
It's not the mining that stirs the most concern, but the so-called milling — the separation of the ore from hard rock.
As rock and uranium are mined, they are crushed and then leached through a chemical process to extract the ore. Besides yellowcake, the fuel for nuclear power plants, the process creates huge amounts of waste called tailings. The tailings must be stored for up to 1,000 years. Virginia Uranium, the company seeking the right to mine, has committed to storing the waste in below-ground containment cells that it says would minimize the risk of the radioactive waste being released to local wells or public drinking sources.
